Currency Dropdown (#415)

* Initial dropdown setup and styles

* Allow form field to pass through block content and update dropdown posititon

* add currency to accounts params

* Add repositionDropdown function and carry over dropdown controller

* remove block context from form builder in favour of using form tag directly

* Hide currency input and set checks for input and label before updating

* align currency button with balance

* revert form_field_tag changes

* remove margin on currency button, looks cleaner
